I upgraded ZCS 3 times from 5.016 to 5.018 to 6.0.0 to 6.0.2.
Every time I re-installed the outlook connector, I tried to just install directly the new version (without uninstalling the previous one). And every time this did not work.
I re-tested it today, when upgrading from 6.0.0 to 6.0.2 (server and connector). The pb appens again today.
To make it working, I had to uninstall connector 6.0.2, re-install 6.0.0 (but it did not work anymore)... remove the connector, re-install 6.0.0 (it works) uninstall it again, and install connector 6.0.2. and then it works.
Sorry for not beeing more specific on outlook errors, but in some cases, a window just poped up telling the plugging cannot be used and outlook must be started without the pluggin; in other cases outlook started, but was not able to display any message content...
BTW: This seems to exactly the contrary of the problem reported on Clean uninstallation of Outlook Connector
I am using outlook 2003 SP3 on XP SP3.
Does someone experiment such problem?
